So your site is written for old UAs? Come on! ;)
I tried just to illustrate the point that there are a lot of possibilities  
that other software (proxies, firewalls, antivirus programs...) could  
insert some code at the top of a HTML document. That's the most fragile  
part of any document.

But detecting the document type declaration requires already a parsing. Or  
do I miss something?

I don't know how to do it. But I wouldn't make it irreversible. Why not  
use just the first need of error recovery?

I'm not convinced, but I haven't seen the other proposals. Is there a list  
somewhere?
